Lower Mainland Corrugator Wastewater Reuse Results: (2000 Gallon Batch System)
| Before |
After |
| Needed 3 chemicals: Aluminum Chloride (15 Gal), Lime and Polymer. |
Using 2 chemicals: 50% Sulfuric acid (3 Gal) & Floccin-1106 (35 Lbs). |
| Filter Press: 3 full presses per batch. |
Filter Press: 2 full presses per batch. |
| Frequent need to pressure wash filter cloth & press due to blinding of filter media. |
No need for pressure washing since May, 2005 because of unique chemistry. |
| Need to prepare polymer batch |
No need |
| Need to prepare lime batch |
No need |
|
Benefits: No need for DE Pre-coat, Consistent results, 30% reduction in sludge volume due to drier cake, overall chemical cost is same and significant savings in man-hours.
